The intake water pressure has reduced. - Whirlpool LHW0050PQ Front Load Washer

There should be a water pressure reducing valve in the make up water line. This valve or regulator should keep the boiler pressure at about 10- 12 pounds. It sounds like that valve is letting more pressure to the boiler than it should. There is also an expansion tank that works to keep the boiler pressure at 10 pounds. The rubber seal inside can go bad and the tank will fill with water.

Are you using the same water supply as before when you had good pressure? Some house water lines have pressure reducers to protect your pipes and appliances. This can restrict the water flow and reduce the pressure the machine develops. If the flow surges (good, then weak, then good etc) you are not getting enough water to the pump. Try a larger diameter garden hose (5/8"). If you know where your water line enters the house, try the hose bib closest to it. Often times it is at street pressure instead of (reduced) house pressure.

LF means a long fill was detected. This means that the washer sensor did not sense enough water coming into the unit in the first 8 minutes after starting the wash cycle.

There are several things that you can check. First, make sure that the incoming water pressure is good. You can try replacing the intake hoses and checking the filters on both sides (inside the washer and at the shut-off valves). (When you take the hoses off the shut-off valves, put a bucket under the outlets and check the flow rate.) Some intake hoses will seal themselves if they detect a leak. This will significantly reduce the water flow. If the filters are clogged, you get a similar restricted flow.

Next, check that the end of the drain hose is not positioned below the fill level of the washer. This will cause the water to be suctioned out of the tub as fast as it fills.

If the water is flowing well, the intake valves or the water pressure sensor (which detects the change in the weight of the tub) could be bad or have a wiring harness problem.

I hope this helps.

Could be a bad head or head gasket, but most likely the intake manifold gasket. This is a common problem with this engine. The coolant gets in the intake runner and is sucked into the cylinder. You might try running it a short distance without the radiator cap and see if this reduces the amount of smoke. Less pressure in the cooling system will push less water into the intake. Are you also losing coolant? Let us know if this helps. Robert

sometimes if dishes aren't rinsed well food gets caught in the pump intake reducing flow,try clearing intake of pump

The model you have this listed under WM2688H (LG Steam Washer) a E1 Code Correct water level (246) is not reached within 8 minutes
after water is supplied or it does not reach the preset water
level within 25 minutes.
I suggest you
Check the screens in the water inlet valve for blockage

the water pressure is too high in the intake for your kit. use a higher grade kit or reduce the pressure .

Sounds like too much water pressure or, more likely, the coupler has worn down. You can get a replacement at most hrdware stores.
